Third orbit-raising completed on navigation satellite: Isro

The Indian space agency on Thursday afternoon successfully completed its third orbit-raising manoeuvres of its first navigation satellite - the Indian Regional Navigation Satellite System-1A (IRNSS-1A), said officials.

The orbit-raising activity is done by firing the satellite's on-board motors towards its geo-synchronous orbit at 36,000km.

The IRNSS-1A was launched on July 1 from Indian Space Research Organisation's (Isro) spaceport in Sriharikota in Andhra Pradesh, around 80km from Chennai.

According to ISRO officials, the satellite's onboard motor was fired for around 35 minutes and the result was as per the original plan.

Two more such orbit-raising activities will be made on Friday and Saturday from Isro's mission control facility at Hassan in Karnataka.
